CORPORATION or DELAWARE WIRE JoINING Toot Application filed October 22, 1930. Serial N0 490,431.

This invention relates to wire joining, and particularly to tools for joining wire bindings about boxes, crates and the like.

The primary object of the invention is to provide a twisting tool comprising few parts, and which is constructed and arranged to produce an efficient wire j oinder with a minimum of time and effort, thereby reducing the cost of intertwisting the ends of package 9 binding wires.

lVirebound boxes are usually provided with a plurality of binding wires (at least 3 and usually more) stapled to the box sides. To close such boxes the ends of each binding 13 wire must be intertwisted. Twisting tools have been provided for this purpose having a bored twisting head to receive the wire ends, and two pins or gripping surfaces located in n the bore to engage and intertwist the wires upon rotation of the head, the pins or gripping surfaces being positioned close enough together to hold the wire side and to sever or ring off the wire ends upon completion of thetwist. Difficulty has been encountered in inserting the wires into the end of the bore and between the closely positioned pins or gripping surfaces, particularly when the wires are crimped or bent. It has been pro posed to provide a slotted opening in the side of the head between the pins so that the wires may be inserted from the side of the bore instead of through its end opening. Such'a construction facilitates the insertion of the wires into the bore, but, it has been found that unless some closure for the slot ted opening is provided, the wires frequently move out of the bore through the slotted opening. The present invention is intended to overcome this objectionable feature of the slotted type of twisting tool. 7

One illustrative-tool is shown in'the accompanying drawings, in which Figure 1 is a side elevation. Fig. 2 is an enlarged top view of the nose of the tool.

Fig. 7 is a similar view illustrating the use of the tool in joining the wire ends.

Fig. 8 is a similar view showing the completed joinder of the wire'ends.

Referring to Fig. 1, the illustrative tool comprises a twisting head lv carried by a shank 2, to which a brace 3 may beattached for convenience in turning the tool.

As shown in Fig. 2 the twisting head is bored athpreferably through its central axis, and is provided with two pins 5 extending into the bore on opposite sides thereof and spaced apart in parallelism a distance slightly in excess of the diameter of one of the wire ends to be intertwistcd,-.so that, upon rotation of the head, the wires will be engaged by the pins 5 and intertwisted. Upon completion of the twist the pins 5 function to ring off the ends of the wire,leaving a blunt ended twist.

To facilitate the insertion of thewire ends into the bore 4 and toprevent their dislodgment therefrom after insertion, the head 1 is provided with a slotted opening 6 extending into the bore 4 between pins 5 and atan angle to the longitudinal axis of the bore. lhewidth of the slotted opening 6 is substantially' equal to the distance between the pins 5, and the diameter of the bore 4 is substantially greater than the width of the slottedopening 6, so'that the angled location of the slot 6 leaves a covering portion for the bore at each end thereof, as shown at 7 and 8 in Figs. 2 and 5. Thus, when the wires are inserted at an angle to the axis of the bore through the angled slot 6 and are then straightened in the bore, they are confinedtherein'by the portions 7 and 8,'as shown in Fig. 5.

.- Figs. 6,7 and- 8 illustrate the manner of using the tool. The binding wire ends designated b in Fig. 6 are inserted one at a time 7 through the angled slot 6 into the bore 4 and positioned under the portions 7'and 8. This f in A to

is usually done by the thumbof the operator. The wires are then in the position shown in Fig. 7,.i. e., positioned side by side in the bore 4 between the pins 5 and held in the bore by the portions 7 and 8. The operator then grasps the tool in the manner .shownin Fig. 7 and rotates the head until the twist is completed, as shown in Fig. 8.
